Role of Glycerophospholipids in Membrane Formation

Very Hard Biochemistry Lipids And Membranes

In cellular membranes, lipid composition is critical for their structure and function. Lipids contribute to the fluidity of membranes, play roles in signaling, and form barriers to ions and polar molecules. One of the most studied lipid categories is phospholipids, which exhibit amphipathic properties due to their hydrophilic heads and hydrophobic tails. A particular class of phospholipid, known as glycerophospholipids, is essential for the formation of the lipid bilayer in cellular membranes.

Which of the following statements correctly characterizes the role of glycerophospholipids in biological membranes?

Glycerophospholipids primarily serve as energy storage molecules within the cell.

The hydrophilic head groups of glycerophospholipids engage in hydrogen bonding with water, aiding in membrane fluidity.

Glycerophospholipids can spontaneously form lipid bilayers due to their amphipathic nature, which is crucial for membrane formation.

The fatty acid tails of glycerophospholipids are responsible for the selective permeability of the membrane towards ions.
